Allergy season is getting longer in Nashville and around the nation amid climate change, Axios' Alex Fitzpatrick writes from a new Climate Central analysis.
The big picture: Plants' freeze-free growing season lengthened from 1970 to 2025 in nearly 90% of the 198 cities analyzed in the climate research group's latest report.
- The extended time between the last and first freeze helped determine the length of allergy seasons around the country.
Zoom in: In Nashville, shifting trends added about a month to our annual allergy season, according to the data.
What they're saying: Climate Central vice president for science Kristy Dahl said longer allergy seasons were "a clear signal of a warming world, driven by carbon pollution."
- "As temperatures rise, freeze-free seasons are stretching in every region of the country, giving plants weeks of extra time to grow and release pollen."
- "For millions of Americans, that means earlier, longer, and often more intense allergy seasons that can take a real toll on health and daily life."
What's next: Nashville's unseasonably warm stretch is expected to continue this week, with highs in the next few days pushing toward 80.
